BELIEVING IN DNA
|
A recent issue of Science contained a photograph, made with an
electron microscope, of a portion of DNA extracted from a single-
celled organism called trypanosome.
If you have ever seen the mess a kitten can make of a ball of
twine, this it it. The DNA is twisted into knots and loops as
intricate as a crocheted tablecloth. The author of the article that
accompanies the picture, science reporter Barry Cipra, uses the image
of "an elaborate fishnet." Then he goes on to say, "Yet somehow the
fishnet manages to reproduce itself."
Somehow, indeed!
It has always seemed to me a miracle that even a ...
